Wildhoney · 12-10-2007, 10:27 AM

php Code:

function tinyurl_reverse($szAddress)
{
    $szAddress = explode('.com/', $szAddress);
    $szAddress = 'http://preview.tinyurl.com/'.$szAddress[1];
    $szDocument = file_get_contents($szAddress);
    preg_match('~redirecturl" href="(.*)">~i', $szDocument, $aMatches);
    
    if(isset($aMatches[1]))
    {
        return $aMatches[1];
    }
    
    return null;
}

echo tinyurl_reverse('http://tinyurl.com/388onbs');

Cool, now all we need is a library.

What sort of a library do you think of? A class with the ability to be extended by further link encryption services? If yes, I could contribute some functions but I'm still wondering about the legality of those decryption functions. There are services prohibiting the development and the usage of those 'tools'.
It's not that much work to develop such a class because they are quite simple. I think we only need one method which we pass the URL.
